She was very proud of her husband and rode behind the Saldaean army with all the other wives. She was utterly loyal to her husband only and was cold and untrusting of Rand al'Thor. She met Perrin Aybara for the first time after he had married Faile in Caemlyn and after a few words with him she accepted him as part of the family.

Rand met with Davram after he had been rescued from the White TowerAes Sedai and Deira was present during this meeting. She was worried Rand would send her husband to his death and wasn't convinced that the White Tower had not attached any strings to Rand during his kidnapping.
When Rand initiated the attack on Illian he forbade Deira and the rest of the Saldaean wives from accompanying their husbands into battle, which she didn't seem particularly happy about.

While camped outside Caemlyn, she was attacked and injured by robbers rummaging through her tent. The two escaped but were found later dead outside the camp.

She died alongside her husband during a cavalry charge during the Battle of the Field of Merrilor.
